Technical Field

Background
The BIOS (basic Input Output system), i.e., the basic Input Output system, is a boot program deployed On the ROM chip of the motherboard, and the BIOS is responsible for a computing system Self-Test Program (POST) and a system Self-boot program, and thus is the first program after the computer system is started. The BIOS is stored in the ROM chip and can still maintain the original settings after power is removed.
A BMC (Baseboard Management Controller) is a control unit having an independent power supply and an independent I/O interface, and is disposed in a server, and can control peripherals such as a sensor, a hard disk, a network, and a graphics card of the server. No matter whether the server is provided with an operating system or not, and whether the server is started or not, the BMC can monitor the running condition of the server as long as the baseboard management controller is electrified.
The LPC Bus (Low pin count Bus) is used to connect Low bandwidth devices to the CPU. Common low speed devices are: BIOS, serial port, parallel port, PS/2 keyboard and mouse, and soft disc controller.
IPMI (Intelligent Platform Management Interface) is a set of interactive standard Management specifications for server system cluster autonomy and monitoring physical health characteristics of servers, such as temperature, voltage, fan operating state, power state, etc. Meanwhile, the IPMI is also responsible for recording information and log records of various hardware, and is used for prompting a user and positioning subsequent problems.
